preparation example Construction

[0017] A preparation method of alcohol-free fountain solution, comprising the following steps:

[0018] (1), each raw material is weighed by mass percentage;

[0019] (2), adding each raw material into water in turn, stirring evenly to obtain a mixture;

[0020] (3), the mixture is left to stand for several hours, and then packaged to obtain the finished product;

[0021] (4), the finished product is tested, and after passing the test, it is packaged and stored.

Abstract

The invention discloses an alcohol-free fountain solution. The alcohol-free fountain solution is prepared from the following substances of, in percentage by mass, 20%-35% of water, 0.5%-3% of sodium hydroxide, 1%-3% of sodium nitrate, 1%-3% of sodium citrate, 1%-3% of sorbitol, 0.1%-0.5% of a preservative, 28%-45% of ethylene glycol mono-tert-butyl ether, 1%-4% of a surfactant, 0.1%-2% of a defoaming agent, 0.5%-3% of citric acid monohydrate, 8%-15% of glycerin and 8%-12% of an anti-freezing solution. The alcohol-free fountain solution has the beneficial effects that the alcohol-free fountain solution is simple in material, low in VOC emission, low in soluble element content, small in environmental pollution, green, low-carbon, environmentally friendly and cost-saving, and can replace an alcohol fountain solution widely used in the market.

Description

technical field [0001] The invention relates to the technical field of printing fountain solution, in particular to an alcohol-free fountain solution. Background technique [0002] Fountain solution is a liquid used to moisten the printing plate. Chemical substances and electrolytes are added to the water to meet the requirements of offset printing. Only when the performance of the dampening solution is compatible with the printing machine, paper, ink, etc., can the high-quality products be printed, so that the graphic ink color of the printed matter is bright, the layers are clear, the dots are smooth, no expansion, no shrinkage, no dirty blank parts, and dry imprints normal. The existing dampening solution has high emission of volatile organic compounds (VOC), pollutes the environment, does not meet export standards, and has high material cost. Contents of the invention [0003] The object of the present invention is to provide a kind of alcohol-free fountain solution ...
